BUTTONHOLE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 492,452, dated February28, 1893.

Application filed October 3, 1892. Serial No. 447,605. (No model.)

To all whom t may concern,.-

Be it known that I, ALFRED M. VRIGHT, of McFall, Gentry county,Missouri, have invented certain new and useful Improvements in Scissors,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

The object of my invention is to produce a pair of scissors, simple inconstruction, and adapted to receive extra or auxiliary blades, one ofwhich, when attached to the scissors, will cut in the ordinary manner,and by the removal of this blade and the introduction of another bladespecially adapted, the scissors can be used for the purpose of cuttingbutton holes.

Another object of my invention is to provide means whereby the blades ofthe scissors, while being used to cut button holes, can be gaged to cutthe holes to any desired size or length. I attain these objects ashereinafter set forth and pointed out in myclaims, and illustrated inthe accompanying drawings, in which:-

Figure 1. is an edge view of my improved scissors, the auxiliary bladebeing detached. Fig. 2. is a plan view of a pair of my improved scissorspartially opened, and carrying the blade which is adapted for cuttingbutton holes. This view also shows my gaging device secured to one ofthe shank portions of thescissors. Fig. 3. is a plan view of theauxiliary blade used in ordinary cutting. Fig. 4. is a like View of theauxiliary blade used in the cutting of button holes. Fig. 5. is afrontedge view of Fig. 4. Fig. G. is a perspective view showing the buttonhole auxiliary blade in position on the recessed blade proper, adaptedto receive it. The opposite recessed blade is the companion cuttingblade with the auxiliary blade. Fig. 7. is an enlarged cross sectionalview taken on theline X-X of Fig. 2., but with the scissors shownclosed. Fig. 8. is a cross sectional view on line Z*Z of Fig. 2.

Similar figures refer to similar parts throughout the several views.

The numerals 1 and 2, Fig. 1, designate the Y Shanks and the'recessedblades proper of the improved scissors, pivoted together in the ordinarymanner by a pin, 3, with the auxiliary blade removed.

In my improved scissors the inner faces of the two blades proper arecutaway or recessed their entire length from a point immediately in therear of the pivot, 3, and diagonally across the two blades as shown at 5in the rear of the pivotal pin, thus forming a bearing place for thebifurcated end of the auxiliaryblade when said blade is in position, andat the same time admitting of the free opening and closing of thescissors.

The auxiliary blades, G and 1l, each conforms in shape and size with theopening 4, seen also in Fig. 1., with the exception that it is slightlybroader, as designated at blade proper, 2, at Fig. 2, and its bifurcatedend is of such an angle as to fit and bear against the rear ends of therecesses 18, 18 in the blades proper, and is provided with abifurcation, or slot, 7, which is engaged by the pivot 3 when the bladeis in its proper position for using. Near the pointed end of each of theauxiliary blades is a lag pin, 8,. provided with a head, 9, which headis of .a diameter slightly larger than the lower portion of said lagpin. Near the pointed end of one of the blades proper is a slot, 10,with its rear end enlarged, and of such diameter as to admit the head,9, of lag pin, 8, to pass upward through it. The blade l1, shown in Fig.4., with a deep recess, 12, in its front or cutting edge, isparticularly adapted for cutting but ton holes, but will adapt itselffor light cutting otherwise. Excepting the recess 12, it is identicalwith the blade 6 seen at Fig. 3.

13 designates an adjustable headed notched pin, passed loosely throughan opening in the shank portion of one of the blades proper. Thisadjustable pin is provided with a series of notches, 14. Pivoted to saidshank by means of a screw, 15, in the rear of the adjustable pin 13 is aspring catch, 16, the forward end of which engages the notches 14 in thespring 13. The rear portion of this spring catch 16 is provided withdepending ears, or fingers 17, 17, seen at Fig. 8., which saddles overthe shank 1, seen at Fig. 2, and by reason of the resiliency of thespring 16 is held in position, thereby holding the forward end of thecatch in engagement with the notches 14 of the adjustable pin 13, sothat by lifting the rear end of spring catch from its position on theshank of the scissors, and with a lateral IOO movement either Way itsfront end is disengaged from notches 14 in pin 13, When said adjustablepin can be raised or lowered to suit the convenience of the user. Bythis means the stroke, or cut, of the scissors is limited, diminished orenlarged according to the size of the button hole needed.

To adj ust and readjust the auxiliary blades to-and from the bladeproper, the scissors are partially opened, and the bifurcated end of theauxiliary blade is placed between the two blades proper and against thepivotal pin 3; the pin 8,With the enlarged head 9, is passed up throughthe enlarged portion of slot l0 in the blade proper, then with arearward movement of the auxiliary blade it becomes securely attached tothe blade proper. The scissors are then ready for use according to theblade thus attached. rPhe auxiliary blades are detached by a reversal ofthe above described movement.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A scissors, comprising recessed blades adapted to receive anadjustable auxiliaryl blade provided With a slot or recess in itscutting edge, and a bifurcated rear end, and a lag headed pin near itspointed end, as fully set forth and described.

2. A scissors, comprising recessed blades proper adapted to receive adustable auxiliary blades, provided with a notched adjusting pin, aspring secured to the shank of the scissors, its front end engaging thenotches in the pin thereof, as fully set forth and described.

3. A scissors, having its two blades recessed at their inner sides, anda notched auxiliary blade having a bifurcated rear end adapted to engagethe recess of one of said blades, and an'auxiliary blade having anordinary front cutting surface and having a bifurcated rear en d,adapted to engage the recessed inner face ofthe other blade, and a slotin the outer ends of the scissors blades, and a lag headed pin carriedby the auxiliary blades and adapted to engage the slots in the scissorsblades, substantially as setl forth.

In testimony whereof I afx my signature in presence of two Witnesses.

ALFRED W. WRIGHT.
